A former special education teacher in Montana was accused of repeatedly raping an underage student, officials said.

Rene Elena Carter appeared in court Thursday on felony charges of sexual intercourse without consent, news station KXLH reported. Police said the victim was unable to give consent since he is a minor.

Carter was employed as a teacher at Capital High School in Helena when she allegedly became sexually involved with a male student in February 2015.

Authorities said she had several sexual encounters with the boy until June 7, 2015. Carter resigned from the school district the next month.

Helena Public Schools officials said they were aware of allegations that the pair was sexually involved, but did not find any basis for the rumors.

“The district didn’t just turn its back and ignore its comments,” Superintendent Jack Copps told the Helena Independent Record. “The district did, in fact, try to understand if there was some basis to the rumors out there.”

Carter was booked Thursday into Lewis and Clark County Detention Center and released on her own recognizance.
